Raypak Digital Low NOx Features Low EmissionsThe Raypak Digital Low NOx gas heater complies with the most stringent state and county emissions laws. NOx emissions are less than 40 nanograms per joule.

Fan Assisted CombustionThe Raypak Digital Low NOx is design uses a fan to deliver cool, controlled combustion air to the sealed burners. Other brands use a fan to pull hot flue gases through the heater. The Raypak design allows the RP2100 to outperform others during cold starts and provides longer component life.

Wind Resistant  Built-in Wind Resistant DesignThe Raypak Digital has the best outdoor design in the market today. With over 50 years in designing and building gas heaters, Raypak has put all that experience into its Raypak Digital design. No need for fans to combat drafting problems, the Raypak Digital was designed for outdoor installations with its exclusive low profile design. It is so thoughtfully and carefully designed it actually protects itself from the things that tend to stifle ordinary pool and spa heaters: falling leaves, wind, airborne debris, rain, downdrafts, updrafts, sleet, snow, etc. In fact it is so efficiently designed it ensures uninterrupted heating performance regardless of all but the most extreme weather conditions. Cabinet

 Smart DesignOne look will tell you that the Raypak Digital is different! The look is contemporary. The design is advanced. And inside and out it's engineered to last.

Raypak's original "pagoda top" design will keep the Raypak Digital operating even in extreme wind conditions and downdrafts.

 Polytuff Powder CoatingThe Raypak Digital has a polyester coated, non-corrosive cabinet that is more durable than solventborne and waterborne coated metal cabinets. Every piece of sheet metal that gets powder coated goes through a 7-stage wash system making certain the powder paint has a perfect bond. Underneath the tough and beautiful finish you will find galvanized metal that offers superior rust prevention and years of durable service.

 All Copper Fin Tube Heat ExchangerAll Raypak Digital gas heaters come standard with integral copper finned tube. This means that the fin tubing is made from one piece of extruded copper tube. Since the fins are integral to the tube, maximum heat transfer is attained. Every Raypak Digital has the same robust design tube bundle that we use in our large gas commercial boilers.

 Unitherm GovernorRaypak engineered the Unitherm Governor specifically for pool heater applications, regulating low temperature incoming water, to help reduce condensation. The Unitherm Governor automatically regulates the water flow to help keep the water temperature in the heat exchanger above 105°F. Both water temperature and water flow rate are controlled to eliminate condensation, sooting, and scale buildup that can shorten heater life.

 Automatic BypassNo need to worry about large pumps or high flow systems. The Raypak Digital comes with an automatic bypass built into the header. You'll find that the Raypak Digital delivers the industry's lowest pressure drop and highest water flow rate - up to 125 gallons per minute - exceeding the maximum recommended for 2" plumbing systems. More hot water moves through faster and more efficiently.

 Stainless Steel Tube SheetStainless steel tube sheets are used on all Raypak Digital heaters that use the Polymer resin headers. This allows for a completely nonferrous waterway leaving your pool truly rust-free.

 CPVC 2" Water ConnectionsStandard with every Raypak Digital is a set of 2" slip fit CPVC water connections to make your installation secure and effortless.

 Fuel Efficient Efficient? You bet. Energy-smart Raypak heaters consistently achieve the highest efficiency ratings and the Raypak Digital is no exception. It exceeds all federal and state standards.

Combustion Chamber

 Burner TrayEvery Raypak Digital burner tray is built to last. From the stainless steel burners to the aluminized metal used in the heat sensitive areas. In the event that anything should happen to your burners they can be quickly and easily serviced. One more reason why the Raypak Digital is made to take the work load year after year.

 Fire TileA ceramic fiber combustion box keeps your Raypak Digital running efficiently and keeps the outside jacket cool. By using this space-age material the Raypak Digital won't retain residual heat after it is turned off, allowing it to be installed without the use of costly metal heat sinks.

Quality

 ISO 9001Raypak is proud to be an ISO 9001 registered manufacturing plant. One more reason why Raypak is number one in the heater industry today.

 End-of-Line TestEvery Raypak gas pool heater is plumbed and test fired before it is put in the carton. This ensures that your heater will fire right out of the box and continue to give you years of trouble-free operation.

 Quality CheckpointsThe Raypak assembly process includes 6 final assembly quality checkpoints that help to ensure that each and every Raypak Digital is built correctly, and built to last.

 CSA CertifiedAll of Raypaks products are CSA certified. The RP2100 is tested by CSA to the ANSI Z21.56 standard. Microprocessor Controlled ThermostatThe Raypak Digital gas heater comes with a microprocessor based thermostat control. This control allows you to set your pool or spa temperature precisely at your favorite setting just by pressing an up or down temperature control button. The Digital display gives you a constant read out of your pool water temperature. Just set it, and forget it! Truly simple.

 Self DiagnosticTroubleshooting a gas heater has never been easier. The Raypak Digital has on-board diagnostic controls that let the user and the service professional know what is going on with the heater at all times. In the event that you would ever have a problem with the heater, the digital display will show where the problem is in the control circuit. It's like having a service technician built into every heater!

 Remote CompatibleThe Raypak is compatible with most major pool control and remote systems on the market today. Any two-wire or three-wire remote can connect to the Raypak Digital and be integrated into the pool control system of your choice.

 Electronic IgnitionRaypak Digital heaters come standard with intermittent spark ignition pilot safety controls. What this means is that the pilot only comes on when there is a call for heat. This is a more energy efficient way to control you heaters gas usage by not having a standing pilot. Raypak has been using the same reliable electronic pilot ignition design for over 20 years.

 How to Choose the Right Size Heater: Proper heater size is based on the time required to heat pool or spa. If water is heated for each intended use, energy-saving rapid  heating may be appropriate. If water is gradually heated to the desired temperature and then  maintained at that temperature, a smaller heater may be acceptable.

IMPORTANT Notes:Gas Heater Installation - Upon delivery of unit, installation of a heater can be performed by homeowner, but The Energy SuperMarket stronglyrecommends the installation of any new or replacement gas heater be done by trained personnel, a licensed and insured contractor, or by a pool/spa professional.Gas Connections - Actual hook-up of the gas connections and the turn-on of the gas itself are highly recommend, and in most states legallyrequired, to be performed by a licensed and insured plumber, or a gas utility company employee.

CriticalWarning - Do not attempt to connect gas lines or turn-on gas yourself! Serious personal injury, damage to the unit and/or home, fire, or explosion could result !!!___________________________________________________________

What is NOx?NOx is the generic term for a group of highly reactive gases, all of which contain nitrogen and oxygen in varying amounts. Many of the nitrogen oxides are colorless and odorless. However, one common pollutant, nitrogen dioxide (NO2) along with particles in the air can often be seen as a reddish-brown layer over many urban areas.

Nitrogen oxides form when fuel is burned at high temperatures, as in a combustion process. The primary sources of NOx are motor vehicles, electric utilities, and other industrial, commercial, and residential sources that burn fuels

Where does it come from? NOx form when fuel is burned at high temperatures, as in a combustion process. The primary sources of NOx are motor vehicles, electric utilities, and other industrial, commercial, and residential sources that burn fuels. Utilities: 27% Motor Vehicle: 49% Industrial/Commercial/Residential: 19% All Other Sources: 5%

NOx is one of the main ingredients involved in the formation of ground-level ozone, which can trigger serious respiratory problems. NOx: Reacts to form nitrate particles, acid aerosols, as well as NO2, which  also cause respiratory problems.  Contributes to formation of acid rain.  Contributes to nutrient overload that deteriorates water quality.  Contributes to atmospheric particles, that cause visibility impairment  most noticeable in national parks.  Reacts to form toxic chemicals.  Contributes to global warming.

NOx and the pollutants formed from NOx can be transported over long distances, following the pattern of prevailing winds in the U.S. This means that problems associated with NOx are not confined to areas where NOx is emitted. Therefore, controlling NOx is often most effective if done from a regional perspective, rather than focusing on sources in one local area.

NOx Emissions are increasingSince 1970, EPA has tracked emissions of the six principal air pollutants - carbon monoxide, lead, nitrogen oxides, particulate matter, sulfur dioxide, and volatile organic compounds. Emissions of all of these pollutants have decreased significantly except for NOx, which has increased approximately 10 percent over this period.

Health and Environmental Impacts of NOxNOx causes a wide variety of health and environmental impacts because of various compounds and derivatives in the family of nitrogen oxides, including nitrogen dioxide, nitric acid, nitrous oxide, nitrates, and nitric oxide.
